Hi David,
i take the time to verify that my eproms in the counter where really
Am29F010B-45jc.
OK, i would be happy to have the "good image files you generated from good
parts".
The HP-reference of mine are :
U8 53132-80023 3944
U9 " -80024 "
U10 " -80025 "
U11 " -80026 "
The memories (U8) have the refrence :
AM 29F 010B
-45jc
0010 DBA
1998 AMD
So, how can i receive your files?
During the tests i've found an other fail : FR end, but the two entrances
are functionnal, i didn't test as time interval counter.
For the OCXO option, i thought i need a more powerfull PSU than the basic
one...
Thanks in advance
Best regards
Alain
F4GBC (Ref 55987)

Hi Alain
I can't help with the differences in the PSUs, there is little you can
tell
by looking at the unit. I wonder if it might be easier to run the OCXO
from
a new additional supply housed in the unit, there appears to be space for
this (?) and feed the 10MHz into the external REF I/P? There are options.
effectively, at power on, i have a message : rom failed, but
it seems to have no importance, since after actioning the
run touch, it works well (why ???). Do you really need an
image of the eprom ?
Regarding the eproms, your fault description matches what I've seen in 3
or
4 units, all at first glance functional. The worry is that the fault
clearly
was not there a few years ago and you have got to assume the worst, why
should it stop degrading? The blank parts are Am29F010B flash and were
cheap
and available when I looked. Let me know if you want the image files I
generated of good parts emailed, the set of images etc in various formats
is
about 1.7M (4 parts in 3 different file formats).
David
